Texas Instruments 14-pin (2.54mm) Converter Converter
|
Targets based on Texas Instruments (TI) ARM microcontroller can feature Texas Instruments Arm 14-pin target debug connector with the TI the proprietary pinout. A converter connecting at the end of the 20-pin 2.54mm Arm Debug Adapter is available for Arm 14-pin pinout. Make sure you don’t mix up TI pinout with the standard 14-pin 2.54mm Arm Debug Adapter (Ordering code IC50112).
The following pinout is valid on the target side:

14-pin TI Arm pinout
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
If the jumper on the converter is populated, the SYSTEM RESET line is connected to pin 14 on the target side. If SYSTEM RESET is not needed, the jumper should be removed.
The converter connects to the target via a 14-pin 2.54 mm connector, for example Yamaichi FAS-1401-2101-2-0BF. A target should feature a matching part, for example WÜRTH ELEKTRONIK 61201421621.
|
This converter is used only in conjunction with the 20-pin 2.54mm ARM Debug Adapter (Ordering code IC50111-1). |
|
Make sure this adapter fits on your target connector - check Cross Table. |

Refer to Hardware Setup and Configuration Tutorial to get more information on how to connect the hardware. |
